With the development of China&#8217;s auto industry and the improvement of energy saving and emission reduction requirements, the application of powder metallurgy technology in the automotive industry. More and more, more and more metal parts will be produced by powder metallurgy. At present, the average powder metallurgy product usage per car in Europe is 14kg, Japan is 9kg, the United States has reached 19.5kg or more, and it is expected to reach 22kg in the next few years. At present, the average amount of powder metallurgy products per automobile in China is only 5-6 kg. Considering the factors of energy saving and emission reduction, domestic enterprises will use more powder metallurgy processes to produce auto parts in the future.<\/div>\n<div>S\u1ef1 ph\u00e2n b\u1ed1 c\u00e1c b\u1ed9 ph\u1eadn luy\u1ec7n kim b\u1ed9t trong \u00f4 t\u00f4 \u0111\u01b0\u1ee3c th\u1ec3 hi\u1ec7n tr\u00ean H\u00ecnh 2.
